I just recently got a Revopoint Pop 2, and I've been thoroughly impressed by it. I feel anyone looking at 3D scanners needs to keep expectations in check (they are not magic), and it takes work to get good scans, but personally I think it's well worth looking at Revoscan. For hand size and up, the Pop 2 or Pop 3 are great size. The mini is for very small objects, and I'm not sure of the Range can do that small (but it looks SIGNIFICANTLY better for larger objects). I've only had it for a week, but do you have any questions on it?
Also, check their ebay store. I got the Pop 2 openbox that way directly from Revopoint, and it was only $350 for the base, or $400 for the complete kit with turntable, battery bank, and case. The turntable alone is DEFINITELY worth the extra $50.
Here are some screenshots of scans. The head is my scan of the included sample part, and the 1 2 3 block is a machinist tool that is exactly 1 x 2 x 3 inches. I 3D printed it, and with calipers it checked about .010" off per 1", or roughly 1% "small". That is with zero CAD work or scaling.
Okay so here come the questions!
So with the POP 2 - just so I am clear: You do not have to use it with any sort of mat or table right?
Also couple issues I have had that was frustrating with the phone apps that I was wondering about the Revopoint:
When scanning with the phone apps you get an error waaaay too easily if your hand slightly tilts the wrong way or you get going too fast (see my sarcastic first post). I had gotten around this by rigging the phone up to not move and rotating the objects I scan but 99% of the objects I want to scan are too large to do this with. I was wanting something that I could handhold scan without the headaches mentioned or at least a lot less.
How are the meshes? The ads made them look really good. I will admit the ones I got off the last app I had tried we’re fairly decent - it was just a matter of getting the scans done which were extremely frustrating.
I do not intend on using it with very small objects just stuff say anywhere from 6 inches up to human size that I would print on an Ender or resin printer if mine depending on what it was scanned.
Have you tried the reality scan app by Epic games? I did not get great results from the one scan I tried, but I've seen really good scans, and it doesn't care how fast you go or what direction.
That being said, as long as the revopoint keeps tracking: no errors. The only times I've had it lose tracking were when scanning a 1 2 3 block without spray (shiny metal) and when trying to scan my car dash in a fairly dark garage (high gloss black). For anything shiny and maybe very dark, you need spray of some sort; either the purpose made stuff or talc free foot spray.
The meshes can vary from mostly smooth with some bumps to kind of having a fish scale effect, but the later is from over scanning. Apparently you should always scan either one rotation on the table or only roughly 300 frames at a time for the cleanest result. You can convince as many scans as you want though. As I said below I'll screenshots of my results later tonight.
For 6" objects the POP line is perfect. For people or people sized objects the Range looks significantly better, but the range might struggle with 6" objects. I guess it's pretty common for people who get into 3d scanning to have multiple scanners based on what size you are scanning. The POP 2 can scan people, but you have to move a maybe 5x5 or 6x6 "window" around them to get all the detail. The Range had a significant larger view/window to scan people much much faster. The faster you can scan the less likely it is to lose tracking.``
Thanks for the feedback! I might look into this line some more.
I have not had any issues with anything shiny with any apps so far. Perhaps it has just been what I have been scanning? Everything has been either dull objects or flat painted, etc but I will keep that in mind.
Do you have any examples of stuff you've scanned from small large objects? Not the model just a picture of what it generates from the scan for example purposes.
I checked eBay and couldn't find anything except some air safety sensors under "revoscan". When I googled, it looks like the software is RevoScan but the hardware brand is RevoPoimt.
Sorry, it's revopoint not revoscan. It's easy to say the wrong one when all you see if the software day to day... I fixed my comment above. I'll try to get some screenshots up later today, but I've scanned lots of things with the turntable and I scanned my 21 month old when he was asleep on his beanbag.

Yup I found them even I looked for RevoPoint. I was just commenting on case anyone else looked them up.
Actually for me their "range 3d" looks interesting as it seems to be designed with more portability in mind, but I'd love to see models from the other versions too
Quick T Rex toy scan (~4-5" long); the black claws didn't show up. scanned on the side they did, but they didn't merge well. Coelacanth figure again ~5" long. The texture of individual scans on this guy looks amazing, but falls apart when merged together. The mesh itself looked quite decent with the merge though. Both of these could be 3D printed as is.
